The Slug Statue and the Cheese Free-Wheeler seem to be using the Frogborne items instead of the Cheesemoonger items for their buzz bonus.

For example, I can only get Slug Statues and Cheese Wheels that want Water Lilys and Lily Pad Planters (Froggy stuff).

The other Artefacts like the Cheese Strimmer, Cheese Press and Cheese Refiner want Cheese Ore or Cheese Mining Carts (Cheesey Items) like I assume they should.

I feel real silly writing this stuff down.
